A major issue in reading is the extent to which phonological information is used in visual word perception. The present experiments demonstrated that phonological information acquired on 1 fixationâ€¦ (More)

I apologize to the mathematical community that it took so long until this book is made available to a greater audience. Originally I planned to extend the material and present, jointly with Jochenâ€¦ (More)

Several proofs have been published of the mod Z gluing formula for the Î·â€“invariant of a Dirac operator. However, so far the integer contribution to the gluing formula for the Î·â€“invariant is leftâ€¦ (More)

In a series of papers, we will develop systematically the basic spectral theory of (selfâ€“adjoint) boundary value problems for operators of Dirac type. We begin in this paper with the characterizationâ€¦ (More)

We discuss several natural metrics on spaces of unbounded selfâ€“ adjoint operators and their relations, among them the Riesz and the graph metric. We show that the topologies of the spaces of Fredholmâ€¦ (More)

We identify Melroseâ€™s suspended algebra of pseudodifferential operators with a subalgebra of the algebra of parametric pseudodifferential operators with parameter space R. For a general algebra ofâ€¦ (More)

The main purpose of this paper is to investigate the formal deficiency indices NÂ±(I) of a symmetric first order system Jf â€² + Bf = Î»H f on an interval I, where I = R or I = RÂ±. Here J, B,H are n Ã— nâ€¦ (More)
